Enter a name for the script, for example, Empty. Insert Empty Script. Again click the right mouse button and click Invoke Script. Now create a task called Fill. To do this: 7. Enter the name Fill. In the text editor window, click the right mouse button and point to Insert, then click File. With the cursor positioned just above the End statement, insert FillTask. Again click with the right mouse button and click Compile. In the Contents pane of the Simulation Explorer, double-click the task to activate it.

Repeat steps 7 — 10 to create the Heatup, Pcontrol and Step1 tasks. Change the run mode to Dynamic and perform a dynamic run. These steps are automatically performed and the run will stop on completion: 0. The column separates a mixture of acetone and iso-propyl alcohol IPA. The objective is to find the best profile of reflux ratio versus time to minimize the time to separate the mixture, subject to constraints on the purity and yield of the acetone rich distillate. This example is created by starting with an Aspen Plus simulation, exporting this to Aspen Dynamics, and then configuring the simulation within Aspen Dynamics.

The configured Aspen Dynamic file is provided. The procedure may help you in creating your own applications. Locate the example folder BatchDistOpt.

Copy all of the files in the BatchDistOpt folder to a convenient working folder. Load the backup file BatchDistOpt. This creates the file BatchDistOptdyn. Load the file BatchDistOpt. Select Snapshots from the Tools menu. Double click on the result Init to use it to initialize the simulation, and then close the dialog box. Click the run button to run the simulation. To see the progress of the optimization open the Flowsheet plot Reflux.

To find the form of equation used in Aspen, open the Help file, and from the 'index' tab, search for the index for the model name e. You should then see equations very similar to the published literature. To understand where you are within the help file system, switch back to the Contents tab of the help folder and you will see links to the other activity coefficient methods. To verify the pure component values e. Then in the right pane on the 'selection' tab, click the 'Review' button at the bottom right.

These should match the values from the textbook. Click on 'Next'. Stream specifications will appear. You must choose the stream composition, flow rate, and state for feed streams. The state is specified by pressure, temperature, and vapor fraction. For this example, for the feed stream 1 choose a pressure of 1 atm and a temperature of 25 o C.

If you enter feed composition as mole fractions, you also have to specify the total flow rate. Click on Next. The block RadFrac setup will appear.

For this rigorous simulation, you must specify the column configuration. Enter the number of stages as 33 and specify total condenser. Hit 'Next' and the 'Stream' page appears. Locate the feed stream 1 on stage Hit 'Next' to get to the 'Pressure' page.

By leaving the other sections of the pressure page alone, pressure drop through the column will be ignored in this calculation. All required information should now be complete. Click 'Next'.

You should now get a message that all required information has been entered. If you don't, complete the required form or look at the menu on the left for any red semicircles. To run the simulation, click OK on the message, or you can run the simulation on Run in the 'Run' pulldown menu.

To view results, click on the blue folder in the toolbar. Choose 'Stream' to view stream properties, or 'Block' to view column properties. In 'Streams', you can look at the streams you wish and place a streams table on your PFD by clicking the 'Stream Table' button.

In a complex simulation, it is sometime more convenient to work with the PFD to find results. Right-click on a block or stream for a short-cut menu to results. You can bring up compiled reports by going to the 'View' menu and clicking on the desired information.

The information in the reports is controlled somewhat by the report options introduced in Section 4.

You can study the behavior of the column by looking at the column profiles as shown below from the 'Results' data browser. An example table is shown below. For compositions, choose the composition tool, specify liquid mole fractions.

The analysis below shows that there may be more stripping stages than necessary for the given column 33 stages, flowrates, reflux and boilup. Naturally, compositions at the top of the column are limited by the azeotrope. You can print the process flowchart and include the stream table if you have pasted it onto the PDF.

Then select 'Print'. To print 'Input Summary', 'History', or results 'Report' , go to the 'View' menu and select your choice. Save the information as a Notepad. The default reports have more information than you typically need. Avoid printing reports without reviewing them or pasting them in a Word document or you will use up print quota quickly! As you work with Aspen plus and Aspen Properties, saving files in the 'backup' format will assure that they can be opened in the next version of Aspen.

Currently it is not possible to open 'standard' files when upgrading Aspen. The backup format ends with an 'bkp' as the last part of the file extension. You will want to modify your process parameters to run the case again. After modifying, you can click the 'Next' button, or the 'Run' button.

Aspen will 'reuse' the last state to start the next simulation. When a case crashes, this is usually not desirable. Be sure to explore the phase behavior of the systems in your design.

It can be frustrating to try to get Aspen to give a physically impossible result, but many students have struggled with this, and blame Aspen. To see mole fractions of each phase in a mixed stream of multiple phases, you can add mole fractions as property sets for the specific phases.

If these property sets are not available because your simulation did not use the template, you can create custom property sets that include the vapor and liquid mole fractions.

Note that it also possible to add activity coefficients, fugacity coefficients in this manner. To view special properties, create a custom view of the stream report. This assumption can sometimes be used in petroleum processing of hydrocarbons, but is not valid for most functional organics.

When you close the diagram you will find the table with some intermediate calculations. If you would like to get the values into Excel, drag the mouse over the columns, and copy. Then paste into Excel. It is also possible to plot fugacity coefficients, activity coefficients , or other properties as a function of composition or temperature, etc.

Mixture properties typically require that you specify a property set and then 'run' the case. First, specify the components as shown in Section 5. To get properties as a function of composition at a fixed T and P, you will have to set up a property set and then request execution of the set. Give the 'Property Set' a name that will help you remember the calculated properties.

Enter the units if appropriate for your property. On the 'Qualifiers' tab, set the other details for the calculation. In the case of fugacity coefficients, I chose to calculate them for the vapor phase.

The screen will look much like the 'Property Set' page in Section 8. Click 'New' and name the analysis set. I will call mine 'PhiCalc'. Also for most properties you will want to select 'Generic' unless it is clearly an envelope or residue curve. T-x-y, P-x-y and residue curves are accessible more easily as shown in Section 8.

On the 'Systems' tab, if you intend to specify the temperature and pressure, specify 'Point s without a flash'. It will be necessary to set the flow rates even though there isn't any real process stream. On the 'Tabulate' tab, specify the Property Sets for the analysis, and move them to the right list box:. For summary of the output, click the button on the page for 'Table specifications' and give the table a name and specify the precision desired, as shown below.

On the variable tab of the 'Property Analysis' set, you will specify the fixed state variables and the adjusted variables as shown below.

Note that the upper section of the form is for the Fixed state variables, in this case set to be C and 1 atm. The lower table has been edited to vary the mole fraction of acetic acid. Before leaving the form, the values or range for the adjusted variables must be specified. To provide this information, first put the cursor in the variable field e.

Specify the Range or List of Values to be varied as shown below. Here the range will be from 0 to 1 at intervals of 0. Click the 'Run' button on the toolbar. The 'Run' button is the blue triangle in the top tool bar it is 'grayed out' on all screen shots on this web page. You can tell that results are available when the 'Analysis' folder changes to blue as shown below.


The columns of calculations as shown below can be copied to the Windows clipboard by dragging the mouse over the column titles, using the Edit menu or Ctrl-C. The clipboard contents can be pasted into Excel. This section discusses a method to export parameters and import them into a new simulation. As an overview, Aspen Properties files hold all the pure component and binary parameter information, but none of the process schematic information.

They also include information about the property 'methods' including customization of how the vapor phase fugacity is calculated, etc. Plus they hold user parameters that have been used to specify property information and binary interaction parameters.

Resave the properties file after documenting the file. I have not studied these closely, but it in my trials, I had to use 'replace' to overwrite the binary parameters. Also, I did not have the patience to figure out which row in the property list imports the binary interaction parameters. I just used shift-click to select all rows and used the 'replace' button.Heat Exchanger without any static head contributions.
